Your number shouldn't be listed though, as far as I know they can only request your number after they've purchased something from you. Is it possible you've got your number on the first line of your address?

oh my way around it was to get another SIM card and use that for my ebay shop ( a business number if you like)

I have something listed on eBay.

Somehow, someone has been able to get my mobile number from eBay and call me about it.

but only if you're currently bidding on one of their items. That sucks. The guy who called offered cash but I said I wanted more than he wanted to pay so a waste of a phone call.

Looks like I will have to change the registered number to my landline, which doesn't have a phone attached but I will see what ebay has to say first as I wasn't aware they would share all my contact info to anyone.
